<p>A method and an apparatus for delaying parts of a coherent optical signal beam relative to each other, comprising: a first device (104) for splitting the beam into a first part and a second part, a second device (108) for delaying the second part relative to the first part, a third device (106) for recombining the first and the second part, a fourth device (104,106) for providing the recombined parts with different polarizations. <IMAGE></p> |
